I wrote a patch about 6 months ago and got it working perfectly. Just went to use it again today, changed a few parameters and now I can't get it to work.

It's a patch that allows you to load in an image and using jit.matrix extract pixel values and convert them to MIDI notes that are written to a .mid file via makenote and seq. The parameters that I changed are the number of rows and columns in to run through the image and the total counter. When the patch runs, I see all the numbers coming out correctly, and all looks good. When I write the seq, again, all seems ok. When I import the midi file into Logic, sometimes I get a single note instead of the 1180 I expect, sometimes there are multiple notes but they are all the same pitch and the wrong duration.

I can't seem to figure out what I've changed so fundamentally to cause this. Any help appreciated!

Looks like you forgot to adjust the matrix dimensions.

Broc - Thanks, that is definitely something I forgot to switch when I changed images.

Unfortunately, I'm still not able to write out an accurate MIDI file. I've tweaked a few variables in an effort to troubleshoot and clean up the patch. New patch below and I've attached the jpeg file I'm trying to work on.

I just ran a few test runs and one would not open in Logic, one gave me a single note at MIDI value 0 that went on forever, and one test gave me a single note. I'm totally flummoxed!!!

In your patch, the velocity argument 128 of makenote is invalid. It should be 127.

Gah! That did it. Thanks so much! You've been a huge help.

Max7 patch used to work, now won't write MIDI file
